Important safety information:

Omnicef may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Omnicef with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.

Omnicef only works against bacteria; it does not treat viral infections (eg, the common cold).

Be sure to use Omnicef for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.

Long-term or repeated use of Omnicef may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.

Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.

If you are taking Omnicef and a product that contains iron, your stools may turn a reddish color. This is normal and not a cause for concern.
